How to install BFD (Brute Force Detection)

BFD is a modular shell script for parsing applicable logs and checking for authentication failures. There is not much complexity or detail to BFD yet and likewise it is very straight-forward in its installation, configuration and usage. The reason behind BFD is very simple; the fact there is little to no authentication and brute force auditing programs in the linux community that work in conjunction with a firewall or real-time facility to place bans. BFD is available at: http://www.rfxnetworks.com/bfd.php

APF and BFD (BFD needs APF to work) runs completly independent from ISPConfig. You may install it without worrying about breaking IPFC. You just have to turn off the firewall option in ISPC Control Panel before installing APF and BFD. Please do read the MAN pages and look at example config files so that you dont lock youself out.
